The LM2's are good units, but I've had it with the LC1 units ; I had 3 LC1 controllers go bad in less than 2 months. I'm thinking of swapping to a DIY WBO2 for my current build, and either an LM2 or an NGK AFX for other cars.

I don't know people. I checked all my wiring. Didn't change anything but turned it back on and it's working fine. I don't get it.

I will say routing the lc1 are a pain. Also one of my o2 bungs are in the "not nice " position.

I'm gonna dump another couple hundred into the wiring. Between ground lugs, gxl cable and wire wrap it doesn't take much.

If that doesn't get it I will sell what I got and get something that comes with a ready to go harness.

The ECU is fine, I love it. If I can't wire up a good harness then it's worthless. My buddy said he'd come over and help me solder everything up. He is the best at that stuff.

FWIW, what I've noticed when the LC1's fail is that they start reporting funny numbers, then start flashing @ 7.4. Upon closer inspection, you'll notice that the LED won't come on at all if the sensor is connected, but will flash constantly with the sensor unplugged, and you cannot communicate with the LC-1 unit via serial. At first, turning it off and letting it sit will cure it for a little while, but it eventually gets to where nothing will revive it.

I was going to ask if anyone had ever torn apart a dead LC-1 controller and tried to fix it, then Googled it instead.

Swatronics: Innovate LC-1 fix and analysis
Brilliant. I will try this and see if it brings the one I have here back to life. If it does, I'll post the steps I used to bring it back. I'm gonna say I'll be more than a little bit pissed if Innovate is charging $40 a pop to reflash the firmware on a device that loses it because of poor design.

I was a little bit surprised to see that it uses a common Atmel microcontroller. Bosch offers an IC specifically for controlling their wideband sensors and there are other options as well.

Even so, the memory should not be corrupting spontaneously and Atmel typically has their stuff together, so I tend to doubt defective chips....unless Innovate has been using counterfeit Atmel product. (knowingly or not) When you have junk made in China, bootlegs get in the supply chain periodically even when you're dealing with supposedly reputable sources.
Well, reflashing the controller did not solve the issue with the dead LC-1's that I have hanging around. Still the same. As soon as you plug a sensor into them, the LED stops flashing and the sensor never heats up. I still have serial communications, and from that end, it doesn't show an issue. It's almost like one of the circuits or ICs for the O2 sensor has a short in it that kills it. I've visually inspected the entire unit, and can't find any visual faults. I suppose I could reflow all of the joints and see if it's a cold solder joint causing the problem...
